351c Oil Restrictors

The 351c Oil Restrictors are essential engine tuning components for sale for high-performance Ford Cleveland and Modified series engines. These kits are primarily used by engine builders and racing enthusiasts who need to manage oil flow to the top end of the engine during high-RPM operation. By installing these restrictors, you ensure that critical oil pressure is maintained at the crankshaft bearings where it is needed most to prevent catastrophic engine failure.

Manufactured by Moroso, this kit features precision-machined steel components finished with a durable black oxide coating for superior corrosion resistance and longevity. The restrictors utilize an Allen head design, allowing for a secure and straightforward installation into the engine block oil galleries using standard tools. This specific design effectively reduces the volume of oil sent to the lifters and rocker arms, preventing oil starvation at the bottom end during competitive use.

These 351c Oil Restrictors are highly recommended for any Ford 351C, 351M, or 400M engine build intended for drag racing or sustained high-speed performance. Review the technical specifications before you buy to ensure your engine block is prepared for the installation of threaded restrictors to optimize your lubrication system's efficiency. This modification is a critical step in professional engine assembly to protect your investment from premature wear during extreme operating conditions.
